Network Rail Raises Operational Concerns Over Grand Central's Cleethorpes Expansion Proposal

Performance, platform capacity and reliability questioned as regulator considers open access application

Plans by Grand Central to introduce direct rail services between Cleethorpes and London have come under renewed scrutiny after Network Rail warned the proposal could undermine performance and operational resilience on the East Coast Main Line (ECML).

The open access operator is seeking approval from the Office of Rail and Road (ORR) to launch four daily return services linking Cleethorpes with London King's Cross. Under the proposal, trains from Cleethorpes would couple with existing Bradford services at Doncaster before continuing south, with the reverse process taking place on northbound journeys.

However, Network Rail argues that the operational complexity involved in joining and dividing trains at one of the busiest locations on the ECML introduces unnecessary risks to an already heavily utilised railway.

Concerns over Doncaster operations

In evidence submitted to the ORR, Network Rail says the proposed manoeuvre would depend on both train portions arriving punctually before they can be coupled together.

Even under normal operating conditions, it argues, the process would occupy valuable platform space for extended periods, limiting flexibility at Doncaster station and reducing the network's ability to recover from disruption.

The infrastructure manager also highlighted recent punctuality data, noting that since the December 2025 timetable changes, approximately one in ten Grand Central Bradford services have reached Doncaster more than ten minutes behind schedule, while around five per cent have been delayed by over fifteen minutes.

According to Network Rail, those delays increase the likelihood of knock-on disruption if either train portion fails to arrive on time for coupling.

The organisation also warned that any failure during the coupling or uncoupling process could have wider operational consequences, potentially blocking through platforms while trains are moved or taken out of service.

Questions over equipment reliability

Network Rail has also questioned whether the Dellner automatic couplers fitted to Grand Central's Class 180 fleet have been sufficiently proven for this type of intensive operational use.

It says there is limited evidence demonstrating their reliability during repeated coupling and uncoupling movements and believes further performance assurance would be required before such an operation could be introduced.

Grand Central defends the proposal

Grand Central has rejected many of Network Rail's concerns, arguing that the plans have been carefully developed using established railway operating practices.

The operator says Platform 1 at Doncaster was specifically selected because it experiences comparatively low levels of traffic. According to its analysis, the platform is occupied for only around 10% of a typical operating hour, with the proposed Cleethorpes services increasing that figure to approximately 38%, still leaving substantial spare capacity.

It also notes that other operators routinely split and join trains elsewhere on the network without significant operational issues.

Addressing concerns over punctuality, Grand Central argues recent performance figures reflect the challenges associated with the introduction of the December 2025 timetable, which significantly reduced journey times between Bradford and Doncaster.

The company maintains these figures should not be viewed as representative of long-term performance.

It also disputes Network Rail's comments regarding the Class 180 coupling equipment, describing suggestions about its reliability as unsupported and pointing out that Dellner couplers are widely used across Britain's rail fleet.

King's Cross capacity also questioned

Beyond Doncaster, Network Rail has also expressed reservations about the impact at London's King's Cross station.

The organisation believes accommodating four additional ten-car Grand Central trains each day would reduce opportunities to share platforms with shorter five-car services, placing additional pressure on terminal capacity.

As a result, Network Rail has advised the ORR that the proposal would create an unacceptable impact on network performance and resilience at both ends of the route.

Financial concerns raised by Government

The Department for Transport has also voiced reservations, although for different reasons.

While acknowledging that Grand Central's application satisfies the regulatory threshold demonstrating it is not primarily abstracting revenue from existing operators, the department says it remains concerned about the wider financial implications for taxpayers at a time when the railway continues to receive substantial public support.

The DfT also highlighted its backing for East Midlands Railway's plans to improve services between Doncaster, Grimsby and Cleethorpes.

Grand Central has dismissed the department's value-for-money assessment, arguing it is outside the scope of the regulatory process.

Operators fear loss of revenue

Existing operators have also entered the debate.

LNER has raised concerns that the proposed services could divert passengers travelling between Doncaster and London, while East Midlands Railway believes it could lose revenue on journeys between Doncaster, Grimsby and Cleethorpes.

Those concerns will form part of the ORR's wider assessment as it considers whether the benefits of increased competition and additional passenger choice outweigh the potential operational and financial impacts on the wider rail network.

The regulator has yet to announce when it will publish its decision on Grand Central's application.
